Active clinical trials for "Milk Hypersensitivity"

The purpose of this study is to evaluate the impact of a new Amino-acid based formula on allergic symptoms and growth of infants with cow's milk protein allergy and intolerant to extensively hydrolysed formulas;

Primary Endpoint -The percentage of subjects who develop tolerance to cow's milk protein by 12 months post randomization to study formula. Secondary Endpoints Tolerance The transcriptional profile of milk-specific T cells by clinical outcome. Growth and Weight Velocity Stool Consistency and Frequency The estimated frequency of milk-specific T cells by clinical outcome. The TCR diversity of milk-specific T cells by clinical outcome. The milk allergen component-specific IgE, IgG4 and IgA by clinical outcome. Safety The rate of reported adverse events by treatment group.

This clinical trial will evaluate the efficacy of an amino acid formula in infants with allergic manifestations.

There is not enough evidence to support the use of probiotics for prevention or treatment of AD in children in clinical practice. The purpose of this study is to determine whether probiotics is effective in the treatment of atopic dermatitis with cow milk allergy.

The purpose of this study is to describe the symptoms and their evolution up to the age of 5 years in a population of newly diagnosed infants with a suspected or confirmed allergy to cow proteins, for whom the doctor prescribed the Pepticate® Syneo® replacement formula as soon as they were diagnosed. The Pepticate® Syneo® product is an advanced protein hydrolyzate, food type intended for special medical purposes. This is a product already available on the market.

This study of the tolerance and acceptability of an amino acid based feed will assess gastrointestinal (GI) tolerance, product intake and acceptability in relation to taste, smell, texture in 20 patients between 1-10 years currently using or requiring an amino acid based feed for the dietary management of Cows' Milk Allergy and food-allergy-associated conditions, over 4 weeks.

Infants/children with cow's milk allergy will take part in 2 double-blinded placebo-controlled food challenges (DBPCFC) of 2 extensively hydrolyzed formulas in random order. If both food challenges are passed, subjects will be asked to consume the Test formula in an at-home open challenge for 7 days.

Background: Limited published evidence shows specific oral tolerance induction (SOTI) to be a potential intervention option for cow's milk proteins (CMPs) allergy. Our hypothesis is that SOTI should be started early in order to improve its efficacy and prevent CMPs sensitization from evolving towards persistent allergy. The aim of this study was to evaluate the safety and efficacy of SOTI in 2-year-old children with cow's milk allergy, as a treatment alternative to elimination diet. Methods: A total of 60 children between 24-36 months of age with IgE-mediated allergy to CMPs were included in this multicenter study and were randomly divided into two different groups. Thirty children (group A: treatment group) began SOTI immediately, whereas the remaining 30 (group B: control group) were kept on a milk-free diet and followed-up on for one year.

Oral immunotherapy (OIT) programs for milk, egg and peanut, desensitize patients to their respective allergens and thereby decrease their risk of morbidity and mortality. OIT programs, however, are not without adverse events, particularly in highly sensitive patients. Recently, it has been demonstrated that the administration of baked milk (BM) products to IgE-CMA patients that are non-reactive to BM, can promote tolerance to unheated milk (UM). The goal of our research is to determine whether BM can promote desensitization even in the highly sensitive patient, who reacts to baked milk as well. In a second step, we hypothesize BM-OIT will promote desensitization to unheated milk, as well. Importance: The change in the risk/benefit ratio of such a program will alter the therapeutic approach to an IgE-CMP allergic patient. Probable implications to Medicine: BM-OIT will allow highly sensitive patients to tolerate milk products, decreasing their risk of life-threatening reactions. Furthermore, analysis of the immune modulation parameters that change during the treatment program, should pave the way for defining mechanisms underlying tolerance in CMP allergy.

Lactobacillus GG (LGG) is able to exert long lasting effects in children with atopic disorders. We have shown that Nutramigen LGG accelerates tolerance acquisition in infants with cow's milk allergy (CMA). The mechanisms of these effects are still largely undefined. The effect of LGG could be related at least in part by the immunoregulatory role played by LGG. This probiotic can balance the generation of cytokines possibly involved in IgE- or non-IgE-mediated CMA (i.e., IL-4, IL-5, IL-10, IFN-γ , TGF-beta, and TNF-alfa), which can contribute to modulation of inflammatory processes. We have demonstrated that children with IgE-mediated CMA produce significantly higher level of IL-4 and IL-13 in response to cow's milk protein, and that tolerance is associated with a marked reduction of IL-13 production and a concomitant increased frequency of IFN-γ releasing cells. Epigenetics studies the heritable (and potentially reversible) changes of the genome inherited from one cell generation to the next which alter gene expression but do not involve changes in primary DNA sequences, highlighting the complexity of the inter-relationship between genetics and nutrition. There are three distinct, but closely interacting, epigenetic mechanisms (histone acetylation, DNA methylation, and non-coding microRNAs) that are responsible for modifying the expression of critical genes associated with physiologic and pathologic processes. The profile of epigenetic modifications associated with Th lineage commitment, coupled with the sensitivity of the early developmental period, has led to speculation that factors that disrupt these pathways may increase the risk of allergic diseases. Specifically, effects on DNA methylation and endogenous histone deacetylase inhibitors acting on specific pathways (Th1 and T regulatory cell differentiation) may favour Th2-associated allergic differentiation. MicroRNAs are another structural components of an epigenetic mechanism of post-transcriptional regulation of messenger RNA translation. It has been recently identified a specific Th2-associated miRNA (miR-21) that is critical for the regulation of Th cell polarization.
